'invention relates to a selvage for a bed spring fabric, the primary vobicct of which is to provide a Yreinforced border,

which is adaptel'dto extend in a plane with the strands ofy the fabric, to form a broad,

flat bearing surface for the 'mattress the edge of the spring.

- A feature of the invention resides in lmeans in the formlof a flat, thin, ribbon like mem-- other suitable material which are positioned and extend ,along either side of thev ribbon like member and which constitute a part of the salvage forv the spring' fabric.-

' In the drawingsformin'g part of. lthis specification:

Fig. I1 is a plan viewofa portion of my' spring, including the'new form of a. salvage for the same. l l Y Fig. 2 is an enlarged detail of a portion of the spring end selvage.

Fig. 3 is an enlarged side view ofyfa" portion of the spring. y

Fig. 4 is a section on the 'line 4 4 of Fig.

1 rig. 2.

In the drawing, the springfA is formed of a series kof loops 112 v'which are made up of individual 'pieces of wire. The loops 12 are ,formed by bending the wire centrally between its ends, to form the parallelly eX- tending strands 13 and 14, while the free vends, of the same are secured together by a f suitable clip 15, so as to rigidly secure the original manner. Y

The spring A 1s made up VVof a series of these loops 12, with the strands 14 and 15 and the'respective loops extendingparallel' toeach yother throughout the breadth of the spring fromrthe fabric of the same. The strands 1 4 'and l5 are @enacted to' ylFig. 5V is a ysection on the line 5-5 ,of

getherbyineansfofthe cross links which strands ,13 and 14`equallyseparated apart at are spaced apart. at intervals'to vholdthe v thepoint ofconnection. `The'rstrands1'3`a`nd 14of the adjacent loops 12 are connected by .the links 18 which are positionedfbetween 'thelinks'lv In thismannerthe respective i strands ofeach'of theloopsare connected alternatively together across the spring A to form ar series of transverely extendingfsupy porting meansatthe various 'points across the surface of the spring. Y v Y The strands'Y 13 and 14 of.l the loops are formed ofwire which is woundl or'wrapped with'a'ser'ies ofY small wires to yform a rope ylike finishl which strengthens the strands y 'and-.provides sufficient roughness'.y to the;

same so that the'connecting links'land .18 remain in their respective positions, after being Vtightly clamped in place. y.Thispre vents thelinks from creeping longitudinally on thestrandsgand also adds' materiallyto these `loopsj12` n f' ,Y

The selvage ofthe spring A is formed 'of two individual strands of wrapped vwire ythe appearance' of the fabric. made `up'lof 19 and y2() such as are used in making upthe .loops 12 ofthe ,fabric A.: Thesev v strands 19 and 20 are formed with eyelets 21 andv22 respectively and ends 23 which extendbeyond the eyelets on either end of the strands.` The strands 19 and 2Ov are heldspaced apart and supportedon theirV endsby helical Coil springs 24. 'The ends 23 of the strands 19 and 20 extend into the coilsof the springs' 24 and form supporting means" to strengthen the eyelets V21 land22. This form of construction is geconomiealand cheap toA manufacture, forming a durable construction, as itv is :impossible forv the eyelets 21and 22 to become' enlarged due to the ordinary strain in use, owing to the lsupporting ends 23. This construction' also Vprotects the bed clothing against engage-k ment with the ends'23 which wouldbe aptv to tearl the mattress or bedding and thus befimpractical in connectionwith the use of the fabric. -Itishighlyl desirable to make up the Ventire fabricv with 'noy un-V nished edges and in lmy invention"y I am endeavoring'V Vto accomplish this vinapneat practical way,-.

A flat ri bon 'like` strip 25 Ais interposed between the Strands v1.9 @M20-and is held,

VOi the same. 'broad supporting; surface the mattress on itsI ends by helical springs '26 which are interposed between the springs 24 yand-1n close proximity to the same. V'lhe strip 25 is held in flat relation with? `and approiiwhich iis strong and durable and inalies a Geli/:age for ithe f'tabricoit the spring,V which with the strands 19 fand 2O :term suiiicient Width to prevent easy bending or twisting of the sel-vage ont of shape when .thespring .isili nse. fllhisspfingzis economi-salto manufacture and its neatness in ydesign is very desirable for a springiot tliislnature.

Thestrands 19 and l20 forni guards for leither side 'ofthe strip 2.5. This'is essential to. protect the "mattress .and bed clothing "from thefedge oi" the strip V25. The connecting links I27 held the strip 25 to the guard strands 1'9 Iand `20 lso that the saine remain approximately in a ysingle plane. :In 'this manner the istrip '25k ycannot vtwist so -as to project its` longitudinal edges above the Vguard strands and thus forms a substantial reinforced selvage for the spring;

l claim:

l A selvage for bed springs, including 'a pair of Wire strandseiitendingfinparallel relation to eachother, a'lat.strandinter-y posed between said Wire 'strands5 :pairs of vcross links connecting said Wire strands,

said crosslinks being` of similar formation and closely spaced and an oisetttormedxin said dat strand adapted to llie between said pairs lof connecting 'links7 rwhereby vsaid sables be maintained in `alineinent.

selvage for .a bed `spring fabric conipositionedbetweenlsaid spaced cables and pairs ot connecting links secured #to Asaid 4cables lying vadjacent one another, one of said links being' positioned below andthe other above said flat strip and recesses i'oiined in said eonneeting'linlstor holding sai@ 'dat strip in proper relation to `said cables and an offset formed in rsaidfflat stiii'n between said connectinglinls, whereby both links are maintained substantially in the plane of the fabric.
